PORTABLE POWER UNIT.

Application filea October :ia- 192m` zseriai N.f42 0,c81.-

Our invention relates to portable power units and it has particular rclationto `dev Vices ofthe` character designated wherein means are provided in combination. with aV formerfmayvbe operated whilethecarzitself sstanding still and to thiszend. we belt. the

generatorztothe; prime mover at point ahead: Ofthe clutch mechanism.:

Again, wezpropose. to place the'l generator, well; as an instrument board through which;the .circuits from ,said generator are led, `.in a substantially ,water-tight enclosure 'which is. simple;V in construction, and' which admitsofthe top. and front -portions thereof being-;liftedorswung; away fromv the. gen

i erator and panelboardthemselves whereby the latter are ,disclosedto view. The ends of :this housing: are also. detachable to make theinteri'or the'reof even more accessihle, if desired;v

The generatoris mounted in :the bottom of the:housing and; .the instrument ,board overlies.` the samecand is secured within ;the housing` so, that it is 'readily 'accessible' to the operator uponltheiraising' ofthe cover. Suitable, plugs, whereby ;any desired track tools orV lightsimayzbe energized arev 'provided within the enclosure'. Q

The enclosure also` contains a support` for anidler pulley which admits of the generaton'being. beltedV tothe priine moi-'era the .entire generator unit being; tl1ereby:self'con.- tained: and: easily'z'applicable to al section car vof theltype hereinafter descrihed. It should. be noted, however, that while we'have illustrated. the housing; .and` its enclo'sed-;elements'as mounted ona sectioncar lwhcrein a. central portion has two ledge portions `coextensive, therewith, .our invention should not be limited to cars: of-this'characterV since it. is` of vconsiderable benefit when used with any section car wherewith it is desirable to associate a reliable source of. electric energy.l

Referring now to the drawings:

Ffigs. 4, 5, 6., 7 and.`8 are'detail views `of Various portions of the housing; and w 9 is a planzview of the motor car.`

Referring: more 'particularly to'thev drawing, a sectioncarcomprises,Wheels 10 havv i ing axles 11 extending therehetweenp and .upon which is supported'framing'l. A central portion '13, of the car `loody itselfl is Vraised and `has, ledge i portions 11k co-eXtensiVe'V therewith and. positioned somewhat 'below the level .thereof, 'whereby a structureis formedwhereupon.'workmcn sit f while the'caris propelled along the tracks.

A fly-wheel .15 is mounted on a shaft 15a, thelatter being driven by anV engine: lb. This engine is disposed within the central portion 13 of thezc'ar and the shaft l15a is adapted toloe operahlyl associatedfwith the rear Wheelsy of the car Athrough a friction clutch` mechanism comprising a disc 15 carried onthe shaft 15a,` and a disc 1'5d bearingthereagainst and movable along a shaf't 15g, said latter disc| ld. being splined to the shaft .1156 insuchmanner that the latter is driven at'a plura'lityof desired vspeeds `depending'upon the position of the disc' ld. ;Sprocket .Wheels lf and-.15g are mounted upon the'shaft 15e and` the rear axle 11 vrespectively, a driving chain 15h connecting the two. .By means of the mechanism just .described the rear wheel of the caris driven -at anydesired speedor not at all as the case l ;tom fthereofis supported by thelatter and 1.

the back is adjacent the pulley upon the prime mover. The back wall l of the housing isapertured at 19 to admit ofthe passage of a belt 20 therethrough. Side walls 21-21 are adapted to it down over braci:- ets 22-22 attached to a base 23 of the housing and thereby be simply secured in place without the use of bolts or otherwise. A

top Vportion 24 is hinged to a front wall 25u as at 26 and the entire structure so formed may be rotatably moved about a hinge; 27 wherebythe entire interior of the housmg is disclosed. On the front wall of the housing Vis mounted an eye 28 which Vco- Voperates with another eye 29 whereby the movable walls of tle closure can be locked against unwarranted opening. It wilhbe observed that the top portion 24 is provided with lips 30 8O which hold the side walls 21 in place when the front wall 25 1s locked in its down position.

` Mounted'on the base 23 is a dynamo electric machinel having a shaft 32 and 'a driving pulley 83 around which latter passes thel belt 20, whereby the machme 31 may be operated from the prime mover 15. Sockets 34 for the reception vof plugs to which' are attached any desired electrical tools, are also mounted on the base member 23. A bracket 35 is mounted within the enclosure and has an arm 35a which eXtends outwardly therefrom and carries an idler pulley 86 which tends to satisfactorily tighten the belt 20. i TvVithin the enclosure or housing 17 is posltioned a framing consisting of uprights 37 and cross pieces 88 extending itherebetween, this frame serving as a support -for an inf strument board 39. On the latter aremounted any desired instruments, here shown as a meter 40, a field control rheostat 41, and a pair of switches 42 through which are led the circuits which 'terminate in the sockets 34. i

The belt 20 is shown as having its ends secured together by a fastening device or lacing 20a, by means of which the belt may be removed from the pulleys 16 and 33 and the entire housing and its contents thereby Vrendered independent and removable as a unit from the section car.. i

It will be seen from theforegoing description that we have placed upon a railroad section car a very desirable adjunct and have associated the same with the car in 'sucha way that thel space it occupies is substantially negligible. Moreover, we have providedV a particular wa'terproof housing and have so formed the latter that one locking device is sufiicient to prevent tampering with the interior elements therein although the structure is, alt the same time, by reason vof the particular features heretofore described, of the' knock-down type. It will be seen that, after the cover is raised and `While we have described but one embodia' ment of our invention it is obviousthat many modifications therein may occur to those skilled in the art and that the above disclosure may furnish information whereby many modifications may be made which are within the scope of this invention and We desire, therefore, that the same be limited only by the showing` of the prior art or. by the appendedV claims. l

Having thus describedV our invention, what we claim as new andV desire to secureV by Letters Patent is:

1.
